To ailwhofm 'it may concern.' v.

Be itknoi1vn that I, CAROLINE M. WHEE- Look, a citizen of the UnitedStates, residing at IVashingtOn, Districtof Columbia, have invented certain new and useful Improvenients in Heating Devices; and/I do hereby declare the following to be a full, clear, and exact description of the invenftion, such as will enable others skilled in the art to which it appertains to make and use the same.`

My invention relates to new and useful improvements in heating devices and more particularly to that class adapted to be used in connection with radiators for heating'the contents thereof and my object is to provide means for conveying the product of combustion longitudinally through the radiator.

A further object is topr-ofvide means for` detachably securing the burner in position, and, a further object is to provide means for causing the air and products of combustion to travel in a substantially spiral path when passing through the radiator. v

Other objects and advantages will be hereinafter pointed out and set forth in the v following specification.

In the accompanying drawings which are made a part of this application, Figure 1 is a detail elevation of a radiator showing theheating arrangement attached thereto. Fig. 2 is an enlarged detail sectional view through the radiator showing the manner of attaching the heating mechanism, and, Fig. 3 is an end elevation of the support for the burner and means for causing the air and products of combustion to travel in a spiral path. .u Referring to the drawmgs 1n which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the radiator sections which may be constructed in the usual or any preferred manner and 2 indicates the joints at the lower ends of the radiator by means of which the various sections are lsecured together anda passage for the water provided from one section to the other.

Extending longitudinally of the radiator and through the openings 3 provided by the joints 2 is a tube 4, the ends of which extend "through bushings 5 carried by the outer sections of the radiator, the interior of said bushings having threads 6 with which engage the threads of ringsf7 and 8,

the rings 7 being positioned adjacent the 8 are employed for binding suitable pack ing 9 between the rings and around the tube 4, thus forminga complete-seal around the tube and obviating any possibility of a leakat this point.

Extending into the tube 4 from one end thereof is a burner 10 which may be constructed in any preferred manner, but preferably circular in cross section, gas or similar Icombustible substances being conveyed into the burner from any suitable source and passing through a mixer 11 attached to the projecting end of the burner. burner is heldin position within the tube through the medium of a collar 12, said collar having arms 13 radiating therefrom through the outer ends of which extend screws 14, the inner ends of the screws be- The to hold the collar in alinement with the axial center of the tube. provided in their length with shoulders 16 which engage the inner face of the tube 4 and prevent lateral movement of the collar, and in these shoulders are formed slits 17 which project at an' angle to the trend of the arms and receive the inner reduced ends 18 of wings 19. In the present instance I haveshown but two Wings, but it will be kclearly understood that additional wings may be provided around the collar if found necessary. The object of the wings is to cause the air entering through the end of the tube to travel in a spiral path through tho tube and to accomplish this result the wings are constructed of more or less flexible material so that they can be readily shaped to cause the air to travel in a twisting or spiral path, this action also causing the products ofcombustion to travel likewise, thus throwing the products of combustion to the outer parts of the tube and confining the same against the inner surface thereof, thus obtaining the greatest possible heat from the same. The amount of curvature given the ends of the Wings depends entirely upon the density of the air entering the end of the tube and in View of the iexible nature of the material of which the wings are composed, the curvature may be increased or decreased to accommodate the same lto the class of air entering the tube" thus creating a proper combustion within the tube. The burner 1 0 is provided with a The arms 13 are l plurality escapes,

, While in producing the that but a small amoun of ports 20 through which the gas said ports being arranged in series around the burner and by positioning the-wings adjacent the burner as shown, the

air entering the end of the tube will gather the blaze and carry the same in a whirling motion through the tube as well as thoroughly mix the air with the blaze. The

`burner 1s held against rotatingmovement in any suitable manner, as by means of a set screw 21 which passes through the wall of the collar and binds against the face of the burner. The opposite end of the that occupied by the burner has attached thereto a pipe 22 and if desired said pipe may be extended in'to a flue or through the wall of the building and any suitable means may be employed to control the passage of thle) products of combustion through the tu e. This device can be used for producing either a hot water heat vor a steam heat, the former by substantially filling the radiator with Water, leaving but a nominal space at the upper ends of the sections for expansion, latter a less amount of water is placed in the radiator or only enough to`extend a short distance above the tube in which th@ burner is'vplaced and in view of the manner in which the products of combustion travel through the tube the water in either instance will be rapidly and thoroughly heated. It will further be seen of gas or other heating medium will be required to retain the contents. of the radiator in a heated condition and -thatthe heating arrangement can be attached to any make or size ofradiator atl a minimum expense. What I claim is 1. In a heating device the combination with a. tube and supporting means` therefor,

rounding and a collar surbur'ner 1n the of a burner enterlng said tube positioning the tube from tube, arms radiating from the collar and having shoulders to engage the interior of the tube, said :shoulders having slots therein, means to attach arms to the tube supporting vmeans, and wings positioned around the burner and between the burner and -tube and having one of their ends engaged with said slots, the opposite ends of the Iwings being curved to \cause the flame from the burner to pass thrlugh the` tube in a. substantially spiral pat 2. In a heating device Ithe combination with a tube, means to support the same, and a burner, of a collar to receiveJ said burner, arms radiating from the collar` and having shoulders to engage the interior of the tube, said arms having openings adjacent their outer ends, and screws extending fromv the tube supporting means and engaging said openings in the arms to secure the collar in position.

3. In a heating device the combination with a tube, means to support the same, and a burner, of a collar to receive said burner, arms radiating from the collar and having shoulders to engage the interior of the tube, said arms. having openings adjacent their outer ends, screws extending fromthe tube supporting means and tion, and wings carried by said arms and extending longitudinally of and around said burner, the free ends of said wings being curved to cause the flame from the burner to pass through the -tube in a substantially spiral path.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
